2016-09-27thermal: int340x: New Interface to read trip and notifySrinivas Pandruvada
Separated the code for reading trip points from int340x_thermal_zone_add to a standalone function int340x_thermal_read_trips. This standlone interface to read is exported so that int340x drivers can re-read trips on ACPI notification for trip point change. Also the appropriate notification events are sent by int340x driver based on the acpi event using int340x_thermal_zone_device_update().

Add additional properties: NAME= Thermal zone type TEMP= Temperature sample value TRIP= Violated trip index EVENT= The notification event (new temperature sample, trip violation trip changed) This is the additional information to what kobject_uevent already provides.

2016-09-27thermal: Enhance thermal_zone_device_update for eventsSrinivas Pandruvada
Added one additional parameter to thermal_zone_device_update() to provide caller with an optional capability to specify reason. Currently this event is used by user space governor to trigger different processing based on event code. Also it saves an additional call to read temperature when the event is received. The following events are cuurently defined: - Unspecified event - New temperature sample - Trip point violated - Trip point changed - thermal device up and down - thermal device power capability changed Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>

2016-09-27thermal: Add support for hardware-tracked trip pointsSascha Hauer
This adds support for hardware-tracked trip points to the device tree thermal sensor framework. The framework supports an arbitrary number of trip points. Whenever the current temperature is updated, the trip points immediately below and above the current temperature are found. A .set_trips callback is then called with the temperatures. If there is no trip point above or below the current temperature, the passed trip temperature will be -INT_MAX or INT_MAX respectively. In this callback, the driver should program the hardware such that it is notified when either of these trip points are triggered. When a trip point is triggered, the driver should call `thermal_zone_device_update' for the respective thermal zone. This will cause the trip points to be updated again. If .set_trips is not implemented, the framework behaves as before.

The TSENS controller in 8996 family of SoCs is capable of converting the ADC code outputs to real temperature values (in decidegree Celsius). It can also be programmed to provide raw ADC code, but the secure software on 8996 programs it to provide real temperatures and also does the needed calibrations. We check the valid bit to ensure valid data is read by the AHB master. And the spec recommends the below algorithm to read data 3 consecutive times, which takes care of the worst case delay taken to propagate the updated data to the register.

8960 family of SoCs have the TSENS device as part of GCC, hence the driver probes the virtual child device created by GCC and uses the parent to extract all DT properties and reuses the GCC regmap. Also GCC/TSENS are part of a domain thats not always ON. Hence add .suspend and .resume hooks to save and restore some of the inited register context. Also 8960 family have some of the TSENS init sequence thats required to be done by the HLOS driver (some later versions of TSENS do not export these registers to non-secure world, and hence need these initializations to be done by secure bootloaders) 8660 from the same family has just one sensor and hence some register offset/layout differences which need special handling in the driver.

2016-09-26scsi: Avoid that toggling use_blk_mq triggers a memory leakBart Van Assche
This patch avoids that the following memory leak is triggered if use_blk_mq is disabled after a SCSI host has been allocated by the ib_srp driver and before the same SCSI host is freed: unreferenced object 0xffff8803a168c568 (size 256): backtrace: [<ffffffff81620c95>] kmemleak_alloc+0x45/0xa0 [<ffffffff811bb104>] __kmalloc_node+0x1e4/0x400 [<ffffffff81309fe4>] blk_mq_alloc_tag_set+0xb4/0x230 [<ffffffff814731b7>] scsi_mq_setup_tags+0xc7/0xd0 [<ffffffff81469c26>] scsi_add_host_with_dma+0x216/0x2d0 [<ffffffffa064bef5>] srp_create_target+0xe55/0x13d0 [ib_srp] [<ffffffff8143ce23>] dev_attr_store+0x13/0x20 [<ffffffff8125f030>] sysfs_kf_write+0x40/0x50 [<ffffffff8125e397>] kernfs_fop_write+0x137/0x1c0 [<ffffffff811d8c13>] __vfs_write+0x23/0x140 [<ffffffff811d92e0>] vfs_write+0xb0/0x190 [<ffffffff811da5b4>] SyS_write+0x44/0xa0 [<ffffffff8162c8a5>] entry_SYSCALL_64_fastpath+0x18/0xa8 Fixes: 9aa9cc4221f5 ("scsi: remove the disable_blk_mq host flag") Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Cc: Christoph Hellwig <hch@lst.de> Cc: Martin K.
